ABSTRACT:
A boat hull is constructed of inner and outer aluminum skin layers. A foam material and a plurality of spaced frame members are sandwiched between the two skin layers. The skin layers are directly welded to the spaced frame members, which preferably are spaced apart at close intervals, to ensure structural integrity and product performance. A preferred method of constructing a boat hull designed according to this invention includes providing a temporary support structure that is connected to longitudinal beams of the boat hull frame. After spaced frame members are connected to the longitudinal beams a first skin layer is attached. The temporary support structure is then removed and the aluminum skin layers are attached to the spaced frame members. A liquid, curable, closed cell foam preferably is injected into the spacing between the skin layers and the spaced frame members.
